Abstract
Partial webs are separated in a slitter-winder. The partial webs (WP) are separated by spreading in a spreading device having at least a first, bowed spreader roll () fitted at one side of the partial webs (WP) and a second, bowed spreader roll () fitted at the opposite side of the partial webs. The partial webs (WP) are guided over the bowed spreader rolls () so that the wrap angles (B, B) over the spreader rolls () are substantially unequal. The partial webs (WP) are guided to the first spreader roll () in a lead-in direction (Dinxy) in the XY-direction and the partial webs are guided from the second spreader roll () in a lead-out direction (Doutxy) in the XY-direction such that the lead-in direction (Dinxy) and the lead-out direction are substantially divergent.
